== Summary ==
The Waveshare adapter allows a Raspberry Pi Zero or Zero 2W to be used in place of a Raspberry Pi 3 Model B/B+. It provides four USB ports, a Gigabit Ethernet port and an HDMI port, and its GPIO headers are compatible with 3B-series expansion boards.

== Technical overview ==
* Supports Raspberry Pi Zero and Zero 2W as an alternative to Pi 3 Model B/B+
* Four USB 2.0/1.1 channels for peripherals
* Gigabit Ethernet via RTL8152B chip with one RJ45 port (10/100 M adaptive)
* GPIO header on the Zero board; position matches the physical height of the 3B series, so 3B expansion boards fit directly
* USB switch: switching to 'USB' connects the Ethernet and USB-A ports to the PWR/USB input; switching to 'Zero' connects them to the Zero board
* HDMI port available for video output
* Adapter dimensions are documented under 'Dimensions' in the wiki
* Schematic and official Raspberry Pi documents are available in the Resources section

sudo nano /etc/usb_modeswitch.d/0bda:8151

</syntaxhighlight>

== Notes and version constraints ==
* Ethernet may not be recognized when booting from USB because the chip can act as a virtual CD-ROM on reset – fix via usb_modeswitch configuration
* With Zero 2W: mouse/keyboard unresponsive after switching to 'Zero' due to different USB interface – add dtoverlay=dwc2,dr_mode=host to /boot/config.txt
* Verify exact dimensions and compatibility with specific expansion boards before purchase
* Commands listed assume a Linux system with root access
* Version-sensitive steps (kernel/driver versions) may require manual confirmation
